I have used W-760 & AA 2700 (they're about the same burn rate) with GREAT results in all 3 of my 22-250's... and yes the H-4895 is hard to beat, but the 760 & 2700 meters SO WELL, and I'm getting just as good or better accuracy. I have used H-380, but I ended up with the 760,2700 & 4895.
I use the 760, 2700 in all the 250's and all of my 243's as well! It works for me! I do feel however that the H-4895 is probably less temp sensitive. Good luck, Sam
